. STOVE ATTACHMENT.

To all whom it may concern:

Be it. known that I, .SALv DoI; H .-F1inb; ERICK, a citizen of the United States, residing atSt. .Paul, in the county of Ramsey and State of Minnesota, have invented a new and useful Stove Attachment, of wh ich the following isa specification. j M This invention relates to heating stoves, and the object is to provide a heating stove With eflicient nieans. for circulating the air in a room so as to reheat it, and also to let some of the air pass out of theroom and fresh air enterit, and et heated before 'it spreads in the roorn finother object is to provide a stove with eflicient means-for hu-; midifying the air in the rooni'for rooms warmed by the stove. I u v In the accompanying drawing: 1 Figure 1 ispa top plan viewof a stove provided with .my invention. Fig. 2 is a side'elevation of Fig. 1. Fig. 3 is-a partly sectional front; elevation looking -as from right to left in F 1g: 2, with )IlOSi] "of; the

stove pipeiomitted. Fig. 4 is atop view of the stove and its heating jacket with the top of the latter removed. vFig. .5 is a front elevation of.thejhumidifier'in a modified f r Referring to the drawing by reference nu-, merals, 6, designates the floor and 7 a wall of aroorn in whicha common. heating, stove- 8 is mounted on legs 9. Saidf stove is met.

erably ofthe plain cylindrical typeshown, having 'a fire-pot 10, "an ash-door 11 and an upper cover or lid 12 overthe opening through which the fuel is placed, in the stove. From the top of the stove extends a stove-pipe 13,- which at 14 enters into a chimney concealed in the wall '7. Into the pipe 13 joins at 15 another pipe 16, whose lower end is suspended from the floor and is open and provided with a damper 17'having a handle 18.

(not shown), the pipe 16 is provided with a horizontal branch pipe 20, adapted to be inserted at 19 into the usual stove pipe hole in the closing plate (not shown) of the fire place. Such plate is i, extensively used in houses where a cooking stove is often placedv its base 28.,- as best A'suitable distance upfrom the floor to register witha fireplace Specification of Letters Patent. 1 Pat nt Jul 20, 92 Applic'ationfilqd, January s, 19. 0. serial No. 34953.27/ I I I i the top 22 sheet iron body by screws 24 andv 24 olffqlstiron and secured to the Y The top 22 is provided with a; series of I apertures 25 for the upward escape of the hot air, and in the middle is alargeaperture 26, whoseedge 27 fitsupon the top of the; stove.- i The bott0m.-23 is also provided with acentral aperture ofasizeto fit about the stove between'its fire pot portion and Each end ofthe bottom is provided-with anaperture, 30,] from which extends, down:- wardly a' tube 31 secured by screws 24*: and having a leaf valve 32, fixed on a rockjshaft 33,,having a roekerarm' 34.

.In the jacket 21 are fixed baflle plates 45, spaced directly above the air ports 30, and spaced also some distance from the sides of the stove. Fixed higher up and in alternate or Zig-zag relation to the first men'- cold air 'from the floor may be admitted upward through the tubes 31, and after being tioned baffle plates 'ar e'other baflie plates 46.

In the operation, when the stove is hot, j

fresh air into the. room the valve 37 is. opened and the valves 32 closed. The foul air is gradually used up. as draft air enters into the fire in the usual manner and some of it may also be allowed to .escape into the chimney through the pipe 20 by opening the valve 17. If the draft. through the fire is too strong, valves 17 and 17 may both be not further describe it. 1

'- The lnvention may be considered as an And if this draws too much warm opened a? damper 17 may be air out of the room,

used to regulate the draft up through The. baflle plates .serveto' retard the air tillit gets properly humidifier is already heated. The use of the understood, so I need attachment vto the stove although it may well bebuilt together with the stove if provided before the stove is completed. In either case it will be well to apply it as follows: Put'the pipe 36, 36 withthe tubes 31 in place in the room; 'put the'base and legs of the stove in position; place the bottom 2 3uponthc base and secure thetubes 31' to it by the screws 24, put thelystojve upon the base; put in the humidifier put the jacket 21 in place and secure it by screws 24:; put "the cover 22 upon 'itand i i "120 then put in' place, water poured into the, humidifier, and everything is ready secure it 'by screws 24t The piping 13, '16,

for making a fire in the stove.

What I claimisr 1; The combination with a heating stove, of a jacket spaced about, the stove and having a perforated top, and a bottom' fitting about. the stove closebythe base thereof,

" said bottom having two apertures each with a tube depending below it outside the base of the stove and provided each with a valve,

a T-shaped' pipe having its arms connected one with each of said tubes and its'leg ex tended down" through the floor and arranged to receive fresh air, avalve in said 7 a valve or damper in the leg above the floor, andoperative connec tion between sald valve and the valves in the tubes, whereby the latter valves will 7 close or open automatically in reverse orderto the closingv in the leg.

v2, The structu which the jacket is of oval form and the and opening of the valve said tubes are depending from the parts of its bottom thereby projected beyond the base of the stove. I

3. The structure specified in claim 2, in which the air pipe formed of the leg of the T extends at an incline downwardly with o p itsintake end.
